GPR 을 이용한 자갈궤도 파울링층 파악을 위한 실내실험적 접근

Evaluation of Applicability of GPR to Detect Fouled Layer in Ballast Using Laboratory Tests

초록

Ballast layer requires continuous maintenance. Fouling would be one of the causes that affect irregular settlement. Among various non-destructive methods to evaluate fouling level, GPR was chosen and evaluated through laboratory tests. Permittivity of clean ballast is calculated 3 and frequencies of 900 and 1600MHz were appropriate to detect reinforced soil layer. Fouled layer could be detected by both the frequency well.
